Specification of Letters Patent.

Application filed December 27, 1906. Serial No 349,629.

T all whom it may concern:

Be it known that we, GEORGE S. CoNGER and CHARLES PEARCE, citizens ofthe United States, and residents, respectively, of the borough ofBrooklyn, in the city and State of New York, and of the borough ofManhattan, in the city and State of New York, have invented a new anduseful Improvement in Paper-Feed Mechanism, of which the fol lowing is aspecification.

Our invention relates to paper feed mechanism and more particularly topaper feed mechanism for a printing telegraph instrument, the objectbeing to make the feed positive and, at the same time, prom t, reliableand durable without unduly comp icating the mechanism. I

A practical embodiment of our invention is represented in theaccompanying drawings, in which Figure 1 is a view in side elevation ofso much of a printing telegraph machine as will suflice to illustratethe present invention, Fig. 2 is a horizontal section of the same in theplane of the line AA of Fig. 1, Fig. 3 is a vertical transverse sectionin the plane of the line BB of Fig. 1, and Fig. 4 is a verticaltransverse section in the plane of the line C'O of Fig. 1.

The frame of the machine, as illustrated, consists of a base 1 fromwhich rise plates 2 and 3 for supporting the operating parts. Acontinuously rotating upright shaft 4 driven from a suitable source ofpower, not shown, is supported in brackets 5 and 6 on tending laterallyfrom the plates 2 and carries thereon worm wheels 7 and 8 which gearwith worms 9 and 10 on shafts 11 and 12 for imparting motion to the typewheel shaft 13 and the cam shaft 14, respectively.

The type wheel and the mechanism which immediately coacts therewith topermit it to rotate and to shift the type wheel back and forth along theshaft 13 as well as the cams on the cam shaft other than the cam whichserves to throw the clutch into action for operating the paper feedmechanism are omitted from the present drawings as they form no part ofthe present invention, the present invention being directed solely tothe mechanism for positively operating the paper feed shaft throughconnections with the continuously driven shaft 4.

The paper feed shaft is denoted by 15 and is mounted at one end insuitable bearings in the plate 3 and carries on its end in proximity tothe plate 3 a spur wheel 16. The spur wheel 16 intermeshes with a pinion17 on a shaft 18 mounted in the plates 2 and 3 This sleeve 19 carries aspur wheel 20 which intermeshes with a spur wheel 21 on the shaft 11driven by the continuously rotating shaft 4.

The sleeve 19 also carries at or near its opposite end a ratchet tootheddisk 22.

The sleeve 19 with its spur wheel 20 and its ratchet toothed wheel 22 isfree to revolve under the influence of the driving wheel 21 on the shaft11 without rotating the shaft 18 and hence without rotating the pinion17 and its intermeshing wheel 16 on the paper feed shaft.

When it is desired to feed the paper forward, the sleeve 19 becomeslocked to the.

shaft 18 for a time sufficient to feed the paper the desired distanceforward, usually the space between two consecutive lines, and thissleeve 19 actuated by the shaft 4 through the intermcshing gear islocked to and released from the shaft 18 by means of a pawl, as follows:A pawl 23 is pivoted at 24 to the extension 25 of a collar 26 locked tothe shaft 18 in position to have its hooked end rock into and out ofengagement with the ratchet teeth on the wheel 22. The pawl 23 has atail piece 27 in position to engage a trip arm 28 provided at its freeend with teeth 29 and 30 at different distances from the pivotal pointof the arm 28 and a spring 31 attached at one end to the tail piece 27and at the opposite end to the extension on the collar 26 serves topromptly throw the pawl into engagementwith the ratchet wheel 22whenever the tail piece 27 is released from the tooth 30 on the trip arm28 and hence to lock the rotating sleeve 19 to the shaft 18 causing thelatter to rotate and hence feed the paper forward until the pawl 23 isagain thrown out of engagement with the ratchet wheel 22.

When the trip arm 28 is rocked to the right as the drawing is shown inFig. 3, the spring 31 will throw the pawl into engagement with theratchet Wheel and the pawl together with its support will rotate withthe sleeve 19 until the tail piece strikes the tooth 29 or the tooth 30on the outer end of the trip arm, which en agement will promptly rockthe pawl out of engagement with the ratchet wheel and the feed of thepaper will thereupon promptly cease.

The trip arm 28 is mounted on a rock shaft 32 which passes through theplate 3 where it is provided with an arm 33 subject to be rocked by alever 34 under predetermined conditions as follows :The lever 34 rocksnormally on a pivot 35 by the action of a cam 36 011 the cam shaft 14.The slot 37 in the lever 34 through which the pivot 35 passes iselongated so as to permit the said lever to rock on a fulcrum at or nearone end when the operative parts are in a given position, as forexample, when the tail piece 38 of the rocking dog 39 carried by thedisk 40 on the type wheel shaft 13 is in position to interrupt theswinging movement of the end 41 of the lever 34, (see the dotted lineposition of the tail piece 38 in Fig. 4). l/Vhen the lever 34 and tailpiece 38 are in this position so that the end 41 will engage the tailpiece 38, the lever 34 will no longer be free to rock on the pivot 37but will fulcrum on the tail piece 38 when its opposite end is actuatedby the cam 36 and in rocking on the fulcrum 38, its center portion willswing to the right as the drawing, Fig. 4, is held, thereby rocking thearm 33 and hence the shaft 32 in a direction to swing the trip arm 28out of engagement with the tail piece 27 on the pawl 23.

In practical operation, the disk 40 on the type wheel shaft is under thecontrol of the operator, for instance, the operator at some distantstation in a system of printing telegraph, to be thrown into theposition to arrest the swinging of the lever 34 at pleasure, t'. 6.,whenever it is desired to form a new line or blank space between twolines, whether successive or not, and when the disk 40 is so thrown itwill put the lever 34 in position to rock on this new fulcrum and henceswing the arm 28 in a direction to release the tail piece 27 of the pawl23 allowing the latter to rock into engagement with the ratchet toothedwheel and so cause the paper to be positively fed forward during arevolution of the paper feed shaft. This may be repeated as often as theoperator from the sending station desires and so long as the disk 40 isnot rocked in position to form a temporary fulcrum for the lever 34, thepaper feed will remain out of action and under no tension whatevertending to operate it,

the sleeve 19 during this time working idly on the shaft 18 and theshaft 18 remaining at rest.

What we claim is 1. In combination, a continuously driven shaft, a paperfeed shaft, a sleeve supporting shaft geared to the paper feed shaft, asleeve loosely mounted on the sleeve supporting shaft and geared to thecontinuously driven shaft and means for locking the sleeve to andreleasing it from the sleeve supporting shaft, at pleasure.

2. In combination, a continuously driven shaft, a paper feed shaft, atype wheel shaft, a cam shaft provided with a cam, a rocking levercontrolled by the cam, means connected with the type wheel shaft forchanging the fulcrum. of the rocking lever, a rock shaft controlled bythe rocking lever, a sleeve shaft geared to the feed shaft, a sleevegeared to the continuously rotating shaft and means under the control ofthe aforesaid rock shaft for locking the sleeve to and releasing it fromthe sleeve shaft.

3. In combination, a continuously driven shaft, a feed shaft, a sleeveshaft geared to the feed shaft, a sleeve geared to the continuouslydriven shaft and provided with a ratchet toothed. wheel, a pawl carriedby the sleeve shaft, a type wheel shaft and means under the control ofthe type wheel shaft for throwing the pawl temporarily into engagementwith the ratchet toothed wheel.

4. In combination, a continuously driven shaft, a feed shaft, a sleeveshaft geared to the feed shaft, a sleeve geared to the continuouslydriven shaft, a ratchet toothed wheel carried by the sleeve, a springactuated pawl carried by the sleeve shaft, a rock shaft, a trip armcarried by the rock shaft for operating the pawl, a type wheel shaft andmeans under the control of the type wheel shaft for rocking the saidrock shaft to throw the pawl into locking engagement with the ratchettoothed wheel.

In testimony, that we claim the foregoing as our invention, ve havesigned our names in presence of two witnesses, this fourteenth day ofDecember 1906.
